Simrad Introduces New

Trawl Echo Recorder-

Literature Available

A new Skipper Trawl Eye Sys- tem for echo recordings from the trawl mouth is now available from

Simrad, Inc. of Armonk, N.Y. The system includes a transducer unit for trawl headrope mounting, spe- cial "twin-flex" cable and self- tensioning hydraulic cable winch, and a Skipper 603 six-inch re- corder cabinet, all at a moderate cost.

Designed specifically for mid- water trawl operations, the Skip- per Trawl Eye is said to give an excellent picture of the situation in the trawl mouth. With the transducer pointed downward, the recorder shows fish in the trawl mouth, the trawl footrope, fish below the trawl, and the distance from the trawl to the bottom.

Fishermen report consistently better hauls with the Trawl Eye, since they can adjust trawl depth to the densest part of the fish schools, while keeping the foot- rope off hard bottoms.

The transducer unit consists of a reinforced plastic housing containing a 50 kHz ceramic transducer. A Skipper Model 603 (6-inch) or Skipper Model 802 (8-inch) recorder is used as the

Trawl Eye Recorder. Either can

A graduate of New York State

Maritime College, Mr. Strasser has accumulated many years' ex- perience in engineering design, applied research, and technical project management. In 16 years with Newport News Shipbuilding, he held senior management posi- tions as head of the Engineering

Laboratory, assistant director and later director of research, and fi- nally as engineering projects man- ager on a special project for the

U.S. Maritime Administration.

Earlier in his career Mr. Stras- ser, who started as naval archi- tect at Taylor Model Basin, served two years as an officer in the

United States Navy as hull de- sign officer, Supervisor of Ship- building, New York. He then joined the Marine Division of

Sperry Gyroscope Company, in- volved in the design and assess- ment of ships' anti-roll stabil- izers.

The same age!

So what's the difference?

The headline transducer is con- nected to the vessel by a new type of "twin-flex" cable that is very light, yet has a tensile strength of 1,400 pounds. The ca- ble is run from a small self-ten- sioning winch, normally located behind the wheelhouse, then fed through a stern snatch block that is also supplied with the system.

The hydraulically operated winch is driven by an electric motor from either 220 volts ac 3-phase or 24 volts dc.

Robert Strasser Joins

MacGregor, U.S.A. As

Technical Director

MacGregor Comarain, Inc. of

Cranford, N.J., has appointed

Robert C. Strasser as technical director. The post is considered a key one considering the cur- rently improved prospects for merchant and naval shipbuilding in the U.S., with the consequent increase in opportunity for cargo access equipment suppliers.

Mr. Strasser's appointment re- flects MacGregor Cranford's growing share of the market, which over the past few years has increased in respect of de- signs for both conventional and ro/ro vessels.

Kubota cargo oil pipe after 6 years' use

The pipe above obviously needs replacement, soonest possible, while the Kubota cargo oil pipe, shown below it, still has several years of good service life left. When replacing the pipe in your vessels, consider that Kubota's give more than two times longer service than most others. Fifteen years of use without replacement is ample proof of their superiority. Why?

Kubota materials and methods cannot be found anywhere else in the world. The material is KCP-3L, a chrome manganese steel especially developed by this company. It is made by Kubota's exclusive centrifugal casting techniques, widely acknowledged to be of the highest technological level. The highest degree of weldability gives it the greatest facility of use. That is why fully 95% of all Japanese tankers use Kubota cargo oil pipe. And why shipbuilders and repair docks around the world keep it on hand for installation and replacement.
